摘要
Disclosed is a differential pressure valve comprising: a valve body (111), said valve body having at least one flow inlet (118) and one flow outlet (120); at least one shutter (112), said shutter being movable between an open position and a closed position under a differential pressure across said valve; at least one flow passage (126) from the flow inlet (118) to the flow outlet (120); at least one biasing member (114) configured to bias the shutter (112) towards a closed position so as to block the flow passage through the flow inlet (118). The biasing member (114; 214) is a non-linear biasing member.
